Recently, Tony Blair said the UK should have supported the United States from the start of the Iran war, and criticised the more cautious approach of Prime Minister Keir Starmer. 
What Blair said
At a private event hosted by Jewish News, Blair reportedly argued that Britain should have backed the U.S. military action against Iran immediately. He said:
•The UK “should have backed America from the very beginning.” 
•The U.S. is “an indispensable ally” for Britain’s security. 
•When the U.S. asks for help, “you had better show up.” 
He also suggested the UK should have allowed U.S. forces to use British bases for refuelling and support operations earlier in the conflict. 
Why it caused controversy
•Blair’s comments were seen as criticising Starmer for hesitating before allowing limited cooperation with the U.S. 
•Some ministers pushed back, saying the government had learned lessons from the Iraq War and was being more cautious about military involvement. 
Current UK position (briefly)
The UK has not fully joined offensive strikes but has allowed some cooperation with the U.S. and is conducting defensive operations in the region. 
In short: Blair argues Britain should have backed the U.S. Iran war immediately and been more openly supportive of Washington, while the current government is taking a more limited and cautious approach.
